Is the heyday of China's original advertisements in the Tang and Song Dynasties or the Song and Yuan Dynasties?

Since the Sui and Tang Dynasties, China's feudal society reached its peak, politics, economy, science and technology and culture went hand in hand, and the forms and types of advertisements were also rich and colorful, far exceeding the pre-Qin and Han Dynasties. Teahouses, restaurants, restaurants, inns and bookstores are all over the streets, and the original advertising forms such as mouth names, stereos, signboards, covers, lantern plaques, gatehouses and wine flags have been quite developed in the Song Dynasty. At that time, there were world-famous products, and brand awareness was further strengthened.

Engraving printing invented in Sui Dynasty has developed into movable type printing in Song Dynasty. The breakthrough of printing technology provided a new medium for advertising in Song Dynasty-printed matter. The existing copper plate of "Liu Jinan Jiagongfu Needle" is a very precious historical material of printing advertisements in Song Dynasty.
